brushless dc motor controller manufacturers about their composition and use of brushless dc motor controller manufacturers brushless dc motor controller is composed of main body of the motor and drive, is a typical mechatronics product. The stator winding of the motor to make more balanced three-phase y connection, with three phase asynchronous motor is very similar. On the rotor of the motor with the magnetization of the permanent magnet has, in order to detect the polarity of the motor rotor, inside the motor is equipped with position sensor. Drive consists of power electronic devices and integrated circuit, its function is: accept the motor start, stop, brake signal, to control the motor start, stop, and the brake; Accept the position sensor signals and positive &negative, used to control the inverter bridge on and off of each power tube produce continuous torque; Accept the speed instruction and speed feedback signal, which is used to control and adjust the speed; To provide protection and display, and so on. Brushless dc motor controller has rapid response, large starting torque, rotating speed of from zero to rated speed can provide the rated torque performance, but the advantages of dc motor controller is also its drawback, because the dc motor controller to produce a constant torque under the rated load performance, the armature magnetic field maintain 90 ° with the rotor magnetic field to be constant, this is about to borrow from the carbon brush and commutator. Carbon brush and commutator motor controller rotational motion produced sparks, carbon powder, so besides can cause damage of components, its usage is restricted. Ac motor controller without carbon brush and commutator, free maintenance, strong, wide application, but if you want to achieve the equivalent of dc motor controller according to the characteristic of performance must use complex control technology to achieve. Nowadays the rapid development of the semiconductor component switching power frequency to speed up the many, improve the performance of the drive motor controller. Microprocessor is also more and more fast, which can realize the two ac motor controller to control on a turning shaft in the rectangular coordinates system, appropriate control of ac motor controller in two axial current component, achieve similar control and dc motor controller and dc motor controller performance. http://www。 tcmotor。 Com/foshan electrical and mechanical equipment co. , LTD. , brushless motor controller, brushless dc motor controller, dc servo motor controller, planetary reducer, brushless drive, electrical and mechanical, foshan electrical and mechanical equipment co. , LTD
